1 The Engineering Manual It’s Here! Paul C Czarapata 7/8/2010

2 How did we get here? Good Engineering?  Yes Good Documentation?  Sometimes Consistent from Project to Project?  No To repeat a DOE phrase used about 12 years ago:  “ islands of excellence” Paul C Czarapata 7/8/2010

3 Many Islands – Few Bridges! Information sharing  Largely resides within the particular island  What happens when the device moves to another island?  Little documentation, need for reverse engineering, no idea of what the decision process was => lost time.  Where’s the drawing?  When multiple islands collaborate where does the documentation go?  This problem comes up repeatedly.  Teamcenter Paul C Czarapata 7/8/2010

4 Been there – done that! Don’t do it that way!  “Say we tried that five years ago and it just turned into a real nightmare!” (Lessons Learned) A simple example:  In my early days at the lab (back when the dinosaurs walked the earth!) I discovered some things about instrumentation on a beamline target.  Don’t use plastic limit switches  Don’t use switches that have grease inside  Don’t use ordinary wire with standard insulation Paul C Czarapata 7/8/2010

5 Fast forward A target on a different island was having problems.  The motor would not move the target  They didn’t know the target position Can you guess why?  Folks on that island didn’t hear (or read) what I had learned!  The grease had turned to rock and was holding the switch actuated, making the motor think it was at a limit in the direction they needed to go Paul C Czarapata 7/8/2010

6 So where do we go wrong? Not fully nailing down the requirements and specifications.  Can you say REVIEW? Not paying attention to all important elements of the design.  Gee, I didn’t think about that happening! Not documenting how we came to certain decisions.  I know that napkin with the calculation is here somewhere. Not teaching the end user how to run the system and under what constraints. Not communicating what we learned. Paul C Czarapata 7/8/2010

7 The Manual’s Approach The emphasis ( and responsibility) is placed on the Lead Engineer and their Department Head. There is an emphasis on Review’s  Note: not cost and schedule reviews, real design reviews. There is an emphasis on documentation  Requirements, specifications, design calculations, operations and lessons learned.  Central database for all design information. Teamcenter I heard all the groans… but wait. Paul C Czarapata 7/8/2010

8 What else? The entire manual embraces the “Graded Approach” and the formality of everything is driven by it. DOE did not understand the last version but with Pier’s urging they offered very reasonable suggestions.  A critical comment that we heard was “this is an expert driven manual not a process driven manual.”  After a follow up meeting they said it was not what they were used to seeing but no reason it could not work and work well. Paul C Czarapata 7/8/2010

9 Risk based graded approach The engineer should record, in Tables 1 and 2 below, risk assessment integer values, between 1 and 5, as follows: 1 – low risk 2 – low to medium risk 3 – medium risk 4 – medium to high risk 5 – high risk Definitions of the risk levels are given below with example criteria for risk levels 1, 3 and 5. Levels 2 and 4 are implied to fall between those provided. A – TECHNOLOGY – This defines the degree of technical complexity the Lead Engineer or engineering team will face in executing the project. 1 –The project will use off-the-shelf technology. 3 – Engineers will purchase and modify off-the-shelf technology. 5 – The project will require the development of new technology.

10 Requirements & Specifications Engineering Risk Assessment Requirements & Specifications Review System Design Engineering Design Review Procurement & Implementation Testing & Validation Release to Operations Final Documentation Paul C Czarapata 7/8/2010

11 Some quick notes The manual is purposely brief, on the order of 33 pages. It is not for the new engineer by his or her self. It is intended to be a template for the steps that must be followed. The new engineer will have to be mentored by a more senior (a.k.a. experienced) engineer. There is a large appendix of examples. >200 Pages NOTE: we will be asking for more examples and we see the manual as being a living document. As new examples are submitted we will include them. Paul C Czarapata 7/8/2010

12 Status The Manual is here! The web page for the Official version and the appendices is: AL_Engineering_Manual.pdf Go check out the appendices there is some great documentation in there at: AL_Engineering_Manual_Appendices.pdf There will be a link off the Fermi At Work home page under “Policies and Forms” Paul C Czarapata 7/8/2010

13 Final Words A sincere thank you to: Kathryn Grimm from the Office of Communication. Kathryn is responsible for taking the document from engineer speak to English! Jay Theilacker, my co-leader, who has put a great deal of time and thought into this manual. The entire team for working on the manual.
